VReferring now to the figures, 30 represents a base on which the various mechanisms are assembled. Extending upwardly from the base is a vertical bracket support 3| on which is mounted an electric motor 32 having a cable cord 33 with a plug 34 for connection with a wall receptacle. I'his motor is secured to the bracket support 3| by bolts 35. Upon the upper end of the bracket supportr3| is a shelf bracket 36 secured to the support by bolts 31 and supporting a reduction gear mechanism 38 that is secured to the bracket member 86 by bolts 39, Fig. 2. The electric motor 32 has arpulley 4| that is connected by a pulley belt`42 with a pulley 43 of the reduction gear mechanism 38. The pulley 43 is connected to an input shaft 44 of the gear mechanism 38 and this shaft has a worm 45 that connects with a worm wheel 46. The worm wheel is connected to an output shaft 41 that has an operating cam 48, a cam 49, a cam 50, a cam and a cam 52. These cams are longitudinally spaced from one another on the shaft 41.

Extending upwardly from the base 30 are two transversely spaced parallel'guide plates 53 and 54 providing a slot or space 55 through which paper tape 56 is passed and worked to form the inner package part. This tape is provided by a tape roll 51 mounted on an upwardly inclined plate support 58 fixed at its lower end to the base 30. Also on the support 58 is an idler and tensloning roll 59 over which the tape extends and is directed to the space 55 between the plates 53 and 54. The idler wheel 59 is pivoted on a pin 6| xed to an arm 62, Fig. 7, and pivoted at 63 at'the opposite side of the support 58. The pin 5| extends through an arcuate and elongated slot 64 so that the arm 62 can lie on the opposite side of the support 58 from the idler pulley 59. A tension spring 65 connects with a, pin 68 on the swing arm 62 and is anchored to the inclined vertical support upon pin 81. The spring 65 will keep a tight rearward pull on the portion of the tape which is passed into the space 55. The roll 51 is supported upon pin 68 and will automatically stay in place thereon due to the inclined position of the support 58.

The tape 56 is forced through the space 55 by spaced pairs of driving rollers. The first pair of rollers includes upper and lower rollers 1| and 12, Fig. '1, and the second pair of rollers include upper and lower rollers 13 and 14. On the plate 53 there is journalled a large intermittently rotated gear 15, Figs. 1 and 12, that is operated from cam 49. This cam 49 is in the form of a true eccentric and supports in its ring portion 16 and operating arm 11, the end of which is pivotally connected by a pin 18 to a crank 19 that is pivoted on bolt 8| and which has a spring pressed pin 82 that engages with any of arcuate slots 83 that respectively have closed ends 84, in succession, to step the gear 15 on its pivot connection on the plate 53. A shaft 85 is journalled in the plates 54 and 55, Fig. 13, and the gear 15 is secured to the shaft. The crank 19 is rotatable upon the shaft and will accordingly be worked by the arm 11. The detent end 82 is urged toward a wear plate 86 having the slots 83 and xed to the gear 15 by a compression spring 81 housed within a retaining cup 88 and bearing against the enlarged end of the pin 82.

This gear 15 will intermittently drive pinion gear 89 disposed therebelow and also through this pinion gear there will be driven another pinion gear 99 located therebelow.

The upper driving rollers 1| and 13 are respectively secured to shafts 9| and 92. These shafts in turn respectively have gears 93 and 94 connected thereto. These gears 93 and 94 mesh with the pinion gear B9 to be driven thereby in the same direction.

The lower rollers 12 and 14 are respectively xed to shafts 95 and 96 that have respectively driving gears 91 and 98 which mesh with the gear to be driven by the same so as to have the upper and lower rollers to act in unison to pull and force the paper tape 5S through the space 55. The driving gears 89 and 90 are respectively xed to shafts 99 and |00 that extend through the spaced plates 54 and 55 for journal connection therewith. In this manner, the tape will be advanced intermittently through the space 55. On the roller 1| are converging cutting projections |02 adapted to notch the sides of the tape at two locations, as indicated at |03, and other cutting projections |04 angled therefrom but converging in a different direction provide notches |05 in the side of the tape. Between the sets of notches there is a length |06 that serves to provide the bottom of the inner package part and of the assembly and portions indicated respectively at |01 and |08 outwardly thereof serving to provide the guide side ends of the upper package part, Figs. 7 and 24. The finished upper part is indicated at |08. The formed portions of this upper part |09 are shaped by devices to be presently described and to form portions |06', |01 and |08. The portions |01 and |08' are formed at the same time while still connected and are severed by a knife ||0. The portions |01 and |08 are formed with the parts shown more clearly in Figs. 8 and 9. Upon the base 30 is a plate having upstanding guide posts- ||2 on which a die plate ||3 is supported by compression springs ||4. This die plate contains a die member ||5 adapted to engage with the top face of portion |01 of the paper tape. This portion is supported by a bottom die ||5 having a dovetail formation I6 thereon about which the portion |01 of the paper tape is to be folded to obtain the nal shaped portion |01' and |08.

The die plate ||3 carries operating members |1 and 8 which have respectively opposing inclined faces engageable with pivotable fingers I I9 and |20, respectively, to cause their inward movement over the edges of the tape portion |01 and to force these edges into the cut away sides of the dovetail projection ||6'. These finger projections are pivotally supported respectively on pins |2| and |22 in such a manner that they can pivot inwardly at their upper ends and are restrained against this inward pivotal movement by: `as?telzcslohtsprlngi:fl123:12cCmnttfxdflolilliiOmelia tension z pieces;` |24 .s andi'. |251'. ofi: thfefeingfi These finger-sfere normally-urged tm hein-soute Ward positionseasfxshowfnrin Fie.; .ibMf-the-tenn sion spring.l I 2 3 sand..farefmouedjnwamdly ridgesy sumexpositionsshown 'inlEigi-TQ tdnallysfqrnl. .the portions.: |171 and' |082.'

This pivot arm is xedto ayerticallyextending- .shaft |91, $152,. Atensicnslring l'ijsain'chored- 7 to the under side of the base plate 30 by albolt |99 -and is connected to a pin 200 on the Yarm |95. The vertically extending shaft |91 is journalled in an upstanding sleeve projection 20| on the upper side of the base plate 30 and has a collar 202 fixed thereto by a screw 203. This collar 202 holds the Yshaft |91 on the upper end of the sleeve projection 20| against downward displacement. The shaft |91 will be rotated in the sleeve 20| by'a projection 204 from the collar 202 and having cam follower 205 bearing against the cam.

A tension spring 201 is kconnected to a pin 208 on the lower end of vertically extending lever |82 and is anchored to a pin 209 connected to the bottom face of the base plate 30.

The outer package part |43 is, as shown in Fig. 5, finally located under a support 209. This support has a slot 2 I0 for receiving the finally severed upper package part |09 and spaced cookies |44 disposed on opposite sides of a plunger 2| I which forces thecookies downwardly with the inner packaging part |09 to fold upwardly the end guide portions |01 and |08 and to force the bottom |06' into the outer packaging part |43. The plunger 2|| is shouldered on the opposite sides thereof, as indicated at 2l2, a distance to receive one cookie or equal to the thickness of the cookie. Due to the shape of the end portions |01' and |08' the cookies will be held in spaced relationship at the opposite sides thereof and provide thereby an opening in the package for receiving the ice cream or other filling upon the finished product being delivered from the present machine.

The plunger 2|| is operated by the cam 50 on the shaft 41. Extending upwardly from the plunger 2|| are longitudinally spaced guide sleeves 2|3 and '2|4 which are slidable through a longitudinally extending member 2|5. Above the sleeves 2|3 and 2|4 there is a frame member 2|6 hav-ing depending rods 2|1 and 2|8 respectively for slidably retaining the sleeves 2|3 and 2|4. A block 2|9 is connected between the upper ends of the sleeves '2|3 and 2|4. In this block is an elongated slot 220 to which a pin 22| on the end of a long bent arm 222 extends. This arm 222 is pivoted upon a projection or shaft 2'23 secured to the outer face of the vertically extending supporting plate 53. A boss 224 is provided on the upper edge of the plate 53 to which an anchor pin 225, Fig. 4, is connected. A tension spring 225 is connected to the pin 225 and to a fastening screw 221 on the arm 222. This spring 226 serves to lift the arm 222 and consequently raises the plunger 2| l. The same spring 225 will maintain the arm 222 against the cam 50 and the cam 55 will operate the arm '222 against the action of the spring 226. A spring 228 is connected to a boss 229 on the arm adjacent the pivot shaft 223 to assist spring 226. The upper end of this spring 228 is connected to a pin 230 projecting from a bracket 23| on the upper edge of the supporting plate 53.

The cookies |44 are retained in inclined cookie chutes 234 and 235 provided at their lower ends respectively with a long central slot 238 and two vsmall slots 231 and 238 disposed respectively at the opposite sides of the central slot 236.

In order to retain the cookies while the chutes are located in place in the machine, a gate 239 is provided on the end of the chute. This gate has a handle projection 240 and a pivot pin 24| connects this gate with a supporting projection v1242 on the side of the chute. Once the chutes are in place the gate 239 is lifted.

' These chutes are inclined and in order to 8 straighten the cookies to vertical positions so that they "may be received'by the plunger 2| Fig. 5, brush elements 243 and 244 are used. Guide sleeves 245 and 246 respectively retain the brush elements and the bristles of the brush elements are cut on a bias to enter the large slot 238 of each chute. The brush bristles will act upon the lower edges of the cookies and cause to straighten them and separate them from one another so that they will be evenly fed to the plunger and prevented from jamming.

'I'he brush sleeves 243 and 245 are respectively supported on inclined plates 241 and 248 and respectively having grooves for receiving the sleeves. At the opposite side of each sleeve and in each plate-are spaced small brushes 249 and 250 which are respectively carried in handle elements 25| that are made secure to the plates within holes thereof by set screws 252. These brushes 249 and 250 support the cookies |44 above the slot and in alignment therewith until struck by the shoulders 2 I2 of the plunger 2| To operate the brushes 243 and 244, a lever 253 is pvotally` connected to some part of the frame at 254 and has a rigidly connected arm extending inwardly from its upper end, as indicated at 255, for engagement by a pin 258 extending from plunger 2||, Fig. 4. There is a similar arrangement at each side of the plunger so that the brushes 243 and 244 will be moved inwardly and against the lower edges of the cookies simultaneously with the upward movement of the plunger. The weight of the arms 255 may be suicient to cause slight retraction of the brush elements for the next inward stroke.

The knife ||0 is pivotally connected to a fixed member or the machine and is operated by a link 250 connected at its lower end, as indicated at 259 to the knife ||0 to pivot the same about its pivot connection 260. The upper end of the link 258 is connected to a lever 26| pivoted upon the machine frame and engageable by an abutment 252 iixed to an upstanding projection 263 of the arm 222. Every time the arm 222 is moved down the knife |0 is pivoted upwardly to sever the paper tape side portions. The knife ||0 accordingly is operated when the plunger is operated and by the same main cam 50 which operates the arm 222. A tension spring 254 is connected to the link 258 to normally position and retain the knife I I0 elevated to permit the movement of the formed paper tape therethrough. This spring is anchored to a fixed part of the machine, as indicated at 265.,

While'the cutting operation is effected, the paper tape is locked against any play by a device 258 that is operated by cam 52. This lever device 206 is pivoted by a pin 201 upon the vertical support plate 54. The end of the lever has a hook formation 260 adapted to engage with an arm 269 on shaft 9| of the paper driving roll 1|. A spring 210 acts upon the lever 236 to urge the same toward the cam 52. The lever 256 has a wear plate 21| for engagement with the cam 52. A In order to effect the adjustment of the i'lnal package consisting of inner and outer packaging parts and the cookies, cam 48 through its projection 212A on its side face operates a lever 213 pivoted at 214 on a fixed part 215 of the machine frame whereby to push inwardly a rod 210 slidable in blocks 211 and 218 resting on the machine base 30 and having a plunger member 219 tion under the opening 2|0 of the frame 209 and derange' 9 to makefroom vfor the `making 'offa'nother assembly.
